Coming from someone who's hand has tangled with a power saw, the safety of the SawStop is something I would have if I had the space for it and could afford it. But I can't so I also have the portable version of the Ridgid. Mine's a TS rather than an R model. It's pretty good but has it's limitations. For one, dust collection leaves plenty to be desired, even when the unit is connected to a 2HP dust collector with a 4" hose. Also, handling full size sheet goods with this saw is next to impossible to do by myself, even with rollers and outriggers.
Lowe's and/or Home Depot will cut MDF to reasonable widths I can handle but if I want to use Baltic Birch I have to be able to handle 5'x5' sheets. That's why I would like to get a track saw. While Festool is expensive, I have to apply finish in the same two car garage I make sawdust in so I am saving up for a Festool track saw, sander and HEPA dust collector.
One question would be, how accurate and square does the cut need to be off the saw? While I can get the length real accurate with a few setup cuts, perfectly square is outside the ability of my portable Ridgid so I cut a little large and flush trim. On the other hand, my brother-in-law's professional level table saw is so accurate he can cut inside squares and have them fit perfectly the first time. But then his saw costs at least 5x what mine did and is permanently bolted to the floor.
The contractor version of the Ridgid saw mentioned in the first post most likely provides more accurate cuts than my portable version but my portable version only takes up a few inches of floor space when folded.
